Problems solved by technology

[0004] However, in the process of sprinkling irrigation, due to the increase in the number of coils of the water delivery pipe on the reel, the quick freezing of the nozzle car will gradually accelerate, and the resistance of the water flow in the water delivery pipe will also continue to increase, so that there are nozzles. The pressure of the sprayed water flow becomes smaller, resulting in uneven irrigation

Embodiment 1

[0050] refer to Figure 1-7 , the present Fangming provides a reel-type sprinkling irrigation method to achieve high uniformity, the sprinkling irrigation method includes the following steps:

[0051] S1. Use the tractor to pull the reel type sprinkler irrigation device to the ground, then release the water pipe 5, and use the tractor to pull the sprinkler truck to the sprinkler location;

[0052] S2. Control the water pump 3 and the driving device 9 to work. The driving device 9 drives the reel to rotate and pull the water delivery pipe 5 to rewind to the reel, thereby pulling the sprinkler truck to move. The water pump 3 sends the water to the pressure regulating device 7 after the pressure is adjusted. To spray nozzle 71 to realize sprinkling irrigation;

[0053] S3. In the process of sprinkling irrigation, the first control device 9 receives the detection value of the water pressure measuring device 710, thereby controlling the pressure regulating device 7 to adjust the w...

Embodiment 2

[0070] The invention provides a high-uniformity reel-type sprinkler irrigation device, with reference to Figure 1-Figure 4 , Figure 6 , Figure 7 , as a preferred embodiment, the sprinkling device includes: a chassis 1, the chassis 1 is provided with a reel 2 and a water pump 3, the reel 2 is connected to a driving device 4, and also includes a water delivery pipe 5 and a sprinkler truck 6. The nozzle truck is provided with a nozzle 71, and the chassis 1 is also provided with a pressure regulating device 7, the water inlet of the pressure regulating device 7 communicates with the water outlet of the water pump 3, and the pressure regulating device 7 The water outlet of the water delivery pipe 5 is connected with the water inlet, and the other end of the water delivery pipe 5 is connected with the water inlet end of the nozzle 71, and the nozzle 71 is provided with a water pressure measuring device 710; the chassis 1 A speed measuring device 8 for measuring the recovery spe...

Embodiment 3

[0074] The invention provides a high-uniformity reel-type sprinkler irrigation device, with reference to Figure 5 , which is different from Embodiment 2 in that two support plates 81 of the speed measurement device 8 are arranged in parallel, the speed measurement rollers 82 include two vertically spaced ones, and the rollers of the two speed measurement rollers 82 The surfaces are all arc-shaped, the water delivery pipe is arranged between the two speed measuring rollers, and the first sensor 83 is set to correspond to the two speed measuring rollers one by one. This arrangement can prevent the water delivery pipe from slipping on the surface of the rollers. , by arranging two first sensors, the measured values ​​of the two first sensors can be compared for self-checking, and when the speed measuring roller slips or the sensor is damaged, it can be found in time.

[0075] Further, refer to Figure 1-Figure 7 , as a specific embodiment, the sprinkler irrigation device also i...

Abstract

The invention provides a reel type sprinkling irrigation method capable of achieving high uniformity. The sprinkling irrigation method comprises the following steps that S1, a reel type sprinkling irrigation device is dragged to a field edge through a tractor, then a water delivery pipe is released, and a sprinkler car is dragged to a sprinkling irrigation site through the tractor; S2, a water pump and a driving device are controlled to work, the driving device drives a reel to rotate and drag the water delivery pipe to be rewound to the reel, the sprinkler car is dragged to move, and the water pump conveys water to a pressure adjusting device to be conveyed to a sprinkler after pressure adjustment; S3, in the sprinkling irrigation process, a first control device receives a detection value of a water pressure measuring device and controls the pressure adjusting device to adjust the water pressure, so that the water pressure conveyed to the sprinkler is constant all the time; the first control device controls the rotating speed of the driving device by receiving a detection value of a speed measuring device, so that the recovery speed of the water delivery pipe is constant all the time; and therefore, the sprinkler car advances at a constant speed, the water pressure conveyed to the sprinkler is consistent all the time, and the uniformity of sprinkling irrigation is improved.

Description

technical field [0001] The invention generally relates to the technical field of sprinkler irrigation methods, in particular to a reel-type sprinkler irrigation method for realizing high uniformity. Background technique [0002] High-efficiency water-saving irrigation in agriculture is a major strategic measure to promote the sustainable use of water resources and ensure national food security, water security and ecological security. Water-saving irrigation elders are an effective guarantee for efficient water-saving. Large and medium-sized water-saving irrigation equipment can not only solve the problem of high-efficiency operation of large-scale and intensive agricultural irrigation. Typical mechanized water-saving irrigation equipment at home and abroad include circular sprinkler irrigation machines, translational sprinkler irrigation Large and medium-sized mobile sprinkler irrigation machines such as machine reel sprinkler irrigation machines. [0003] The reel sprinkle...
